    摘要: A differential quadrature phase shift keying (DQPSK) system, method, and device are disclosed. The DQPSK system includes: a transmitter, configured to: pre-code an input first signal and second signal, and generate an in-phase signal and a quadrature signal; modulate the in-phase signal to generate a first differential phase shift keying (DPSK) signal, and modulate the quadrature signal to generate a second DPSK signal; perform a 90 degree phase shift on the first DPSK signal or the second DPSK signal, and interfere with the other DPSK signal to obtain a DQPSK signal; and send the DQPSK signal to a receiver; the receiver, configured to: demodulate the DQPSK signal sent from the transmitter in detuned filter mode, and restore the first signal and the second signal through optical/electrical (o/E) conversion. With the present invention, the accurate control on the phase difference between two arms of an Asymmetric Mach-Zehnder Interferometer (AMZI) is avoided, thus facilitating the signal control and adjustment, and greatly lowering the system cost.

    摘要: Disclosed herein are a process or method for the preparation of prasugrel and several novel crystalline forms of prasugrel hydrochloride. The process comprises preparation of prasugrel by acetylation in solvents which have low boiling point and/or low toxicity, and the process not only avoids using solvents which have high boiling point and/or high toxicity such as toluene, acetonitrile and so on, but also resolves the problem about thermal instability of prasugrel, and the loss of prasugrel is reduced, as well as the yield is raised. The yield of prasugrel is higher than 85% and the purity is higher than 99.5%. The process can prepare prasugrel and its pharmaceutically acceptable salts. The novel crystalline forms of prasugrel hydrochloride are crystalline form H1, H2 and H3, and their performance in oral absorbability, activating metabolism and inhibiting platelet aggregation is excellent. They have a low toxicity and good thermal stability, and are applicable to the preparation of a drug for preventing or treating diseases caused by thrombosis or embolism.
